A novel three-dimensional (3D) nanoarchitecture consisting of hybrid graphene nanosheets (GNs)/graphene foam (GF) was fabricated on the FTO conducting substrate as a high efficient counter electrode (CE) for dye sensitized solar cells (DSSCs). The GNs with various sized such as large-sized heat-reduced graphene nanosheets (H-GNs) and small-sized laser-reduced graphene quantum dots (L-GQDs) were synthesized...
Light-cured composite resins were prepared by illuminating a cylinder with a diameter of 4mm and a length of 6mm for 40s, using bisphenol A ethoxylate dimethacrylate as monomer, triethyleneglycol dimethacrylate as diluting agent, camphoroquinone and dimethyaminoethyl methacrylate as photoinitiators and nanodiamonds as reinforcements. The nanodiamonds were of different size and were surface-modified...
We report a simple approach to reduce graphene oxide (GO) solution by pulsed laser irradiation. The reduction was rapidly carried out at room temperature in only 5min. The reduced graphene oxide (r-GO) was characterized with UV–visible spectroscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, thermo-gravimetric analysis, Fourier transform infrared spectroscopy, scanning...
